Where Did The Moisture Come From?

Examine the weather maps you made (from the page Weather Observations For December 18, 1990). Use the maps to answer the questions about moisture in our area and where it came from.

  1. What was the wind direction BEFORE it began to snow?


  2. What was the wind direction WHILE it was snowing?


  3. What was the wind direction AFTER the snow had stopped?


  4. Would the air from the land be moist or dry?


  5. Would the air from the ocean be moist or dry?


  6. From where do you think the moisture for the snow came?



    7. Go to What Do The Weather Maps Tell Us? to consider some questions about the weather maps you made.

    Return to the page asking "Why Did The Air Turn Cold?"
